Bacterial community structure and soil properties of a subarctic tundra soil in Council, Alaska
The subarctic region is highly responsive and vulnerable to climate change. Understanding the structure of subarctic soil microbial communities is essential for predicting the response of the subarctic soil environment to climate change. To determine the composition of the bacterial community and its relationship with soil properties, we investigated the bacterial community structure and proper...

متن کاملEffects of experimental warming of air, soil and permafrost on carbon balance in Alaskan tundra
The carbon (C) storage capacity of northern latitude ecosystems may diminish as warming air temperatures increase permafrost thaw and stimulate decomposition of previously frozen soil organic C. However, warming may also enhance plant growth so that photosynthetic carbon dioxide (CO2) uptake may, in part, offset respiratory losses. To determine the effects of air and soil warming on CO2 exchang...
متن کاملIncreased plant productivity in Alaskan tundra as a result of experimental warming of soil and permafrost
1. The response of northern tundra plant communities to warming temperatures is of critical concern because permafrost ecosystems play a key role in global carbon (C) storage, and climateinduced ecological shifts in the plant community will affect the transfer of carbon-dioxide between biological and atmospheric pools. 2. This study, which focuses on the response of tundra plant growth and phen...
